Sources Power - On the current source.

           (C) Fedy Savin, 1997



   Radios, amplifiers, televisions,
tape recorders, computers, and many others
electronic devices operate by
electricity consumption. Shorter
speaking, the current source is an integral part of wireless 
devices. 

   That's why your
the first workshop on the road dating from the Radio 
Engineering and will be thesis is toka.Ty sources, I hope you 
know that the current separated by a constant

and variable. With a constant stream of media
electric charges
(Electrons) in a conductor, such as
segment of wire or filament bulbs, included an electrical 
circuit, move all time in one direction. At variable

same current, the electrons in a conductor, or in the
same filament bulbs move alternately in one direction and then 
in another direction. 

In respect elektroosveti network, the current changes
its direction with
at 50 gerts.Gerts
(Hz) is the main unit Measured frequency
1Hz-kollebanie one full second.


  Electric current of tension, measured in volts (V), and 
strength, measured in amperes (A). Measure these

electrical parameters of the voltmeter and
ammeter.


                CATERING

 For experiments that illustrate the principle of action and 
properties of semiconductor diodes and transistors to power 
your first electronic devices that require galvanic cells 
(batteries): 4.5 B, and 9B and best of all take 5V from his 
home computers. In the future we Tell about how build your own 
power supply unit (PSU).
